Ahead of the debate this week it was revealed the LNP Pine Rivers state electorate council emailed MPs warning them they faced preselection challenges if they voted for the legislation.

Ms Stuckey, who is the Member for Currumbin, said she was not worried about a backlash or preselection challenge.

"I've had nothing but support. I had dinner with Deb Frecklington and a number of my colleagues last night and I feel very much that the conscience vote is being respected," Ms Stuckey said on Thursday.
